3. DO NOT push snow in the same direction
causing excessive build up with each succesive
pass.
4. If blade is stored in heated area, allow lawn
tractor and blade to adjust to outdoor
temperature before operating to reduce icing on
the metal surfaces.
ALWAYS LOWER BLADE TO
GROUND BEFORE LEAVING
TRACTOR.
B. Adjust blade spring:
Blade adjust spring tension is adjustable to
permit blade to tilt forward to by-pass solid
obstructions.
KNOW THE TERRAIN. AVOID

may be raised for close work on smooth sur-
faces or lowered to raise the blade to work on
rough or uneven areas. Make sure both shoes
are set evenly and nuts are tightened securely.
_NOTE
Wheel weights and tire chains must
be used with your snow blade for
traction. These accessories are
available at your nearest Sears retail
or catalog store. See page 12.
